.To ah' whom it 'may concern: y

Be, 1t known that I, lViLLIAM DICHMAN N,

a citizen of the United States, and resident of Oshkosh, in the countyof Vv'innebago and State of fisconsiin have invented certain new anduseful.Improvements in Sliding- Shoe Ilurniture Attachments; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claim ofthis specification, its object being to provide simple, economical,antifrictiou and noiseless sliding-shoe attachments for furniture etc.

Figure 1 of the drawings represents a vertical transverse sectional Viewof one of my improved sliding shoe attachments in connection with atubular furniture post; Fig. 2, an elevation of the Aattachment asaforesaid, the furniture post being in section and a grip-spring of saidattachment partly broken away, and Fig. 3, a plan view partly in sectionon the plane indicated by line 3 3 in Fig. 1, a cap shown in this viewbeing partly broken away. c

Referring by numerals to the drawings 4 indicates a flat-bottom diskhaving a preferably curved rim and an upper central hol-y low boss 5,the disk being preferably of glassA or glazed earthenware, andconstituting a sliding shoe of my improved furniture attachment. Thehollow boss of the disk constitutes a flat bottom vertical wall socketfor the lower shouldered end of a stem 6, and in screw threaded orotherwise preferably detachable connection with said boss is a cap 7having a central aperture through which the ,stem extends. From theforegoing it will be understood` that the lower end of the stem hasloose sliding contact with the bottom of the socket portion of the disk.The

lowermost shoulder 8 of the stem 6 serves as a stop in opposition to thecap 7 to prevent a separation of the disk 4 from said stem, and theother stem-shoulder 9 serves as a support for a detachable seat 10 uponwhich to rest a tubular bedpost or other furniture leg 11.

i That portion of the stem between its shoulders 8 and 9 has loose playin the central aperture of the cap 7, and said stem, cap and disk may,for some usages, complete my improved attachment, in whichy there isfree rocking and sliding movement between the disk and stem. Incidentalto rocking motion of the stein G on the bottom of the socket providedfor same, the friction between said stem and disk is lessened inproportion tothe tilt of the aforesaid stem, this being an importantfea-ture of my invention.

The seat 10 supports a bowed plate 12lof sprin metal provided witliacent-ral aperture or the passage of. the stem 6, the ends of said plateor spring being upwardly extended. Another bowed spring met-al plate 13is provided with a cent-'ral aperture for the passage of the stem 6, andit is held on the screw-threaded upper portion of said stem by nuts 14and 15, the'ends of this plate or spring 12 being downwardly extended tolap the ends of the former spring a sufficient distance, both springsbeing under compression in the tubular leg 11 to hold the attachment asa whole in detachable connection therewith. By adjusting the spring 13,on the stem 6, its lap of the spring 12 may be varied to increase ordiminish the stiffness of the two springs with respect to the aforesaidtubular device.

I claim:

A sliding shoe attachment forfurniture etc., comprising a disk havin acentral socket, a stem the lower end o which has loose sliding contactwith the bottom of said socket, and a centrally apertured socket-cap'with the stem, said stem being provided with a lower shoulder inopposition to the underside of the cap. l

In testimony that I claim the foregoing I have hereunto set my hand'atOshkosh in the county of Winnebago and State of Wisconsin in thepresence of two witnesses.
